+1 from me on the Blackguards and brass saddles. Love the look of that Tele too! Very nice :)
The BG will do nasty with the right gain on the amp, but I would imagine not like the Piledriver does. If you value your vintage Tele sound then the BG is the way to go from what I have been told, and it does dirtier sounds too :) Would be interested to know how close to vintage Tele sound the Piledriver gets with the volume rolled off.
